They dont advertise it as an accuracy enhancer, but It seems to work well for me


I got my Model 70 back today, the day after my OPS INC 3rd model suppressor arrived. Beautiful day outside so I closed up shop and headed to the range.




This rifle has always been disgustingly accurate, and the addition of the 3rd model definitely did not hurt anything; if anything it’s shooting tighter!

Having been completely disassembled to contour the barrel for the suppressor I had to re-zero my scope.  It only took a few shots to get where I wanted, and the reduction in recoil makes shooting a dream.

After the initial zero, here are the first 6 shots. I think its 6, I loaded 3 rounds at a time.  I kinda lost count because I kept telling my friend to take a look at the “hole” after each shot.  The bad part was we were shooting into the sun, but the light shined through the holes making them easy to see.  I was laughing out loud as the hole kept getting brighter and brighter..


I got  the elevation fine tuned, so I moved to the windage, in 3 shot groups.  Nice, 6 shots and 2 more holes. Even though this is designed to be shot suppressed all the time, I took the can off and shot 3 more rounds.  POI shift is about 1 ¼” low at 100yds.



And for the final zero check my friend put up an orange dot to confirm with the last round.  Its good.

Nice Steve, I've been interested in the ops 3rd model for a while. Can you show us more of the can and what the barrel profiling looks like?

This is a can for a rifle you intend to always shoot suppressed.  


This mounts right to the barrel threads, no muzzle brake.


Here's what the barrel looks like under the can. With bigger barrels, you can taper the collar into the barrel. With skinny barrels you'll have to add a collar like the 5.56 cans.

Thats nice. Look and feel of a shorter barrel, but the benefits of the standard barrel.

How does it sound compared to a _________ (fill in with whatever you've shot)

Hey. That thing looks familiar.

Everything I've shot, I sell, and no good comes from comparing

I'll just say it sounds good, and I'm very happy with it. Now I can keep my HVT on my AR10, and this on my Model 70.

This is the first bolt gun I have ever shot, gosh I like that thing.

That looks real sweet. Especially on a precision bolt gun the can should just stay on all the time.  Does OPS still make the 3rd model in .223?

Yes, we still make the 3rd in .223.(inventory)

Does the 3rd in .223 have any significant suppression advantage over the 12th model or is it just a lot bigger?

5.56 3rd model on the bottom, 12th model on top.

Oh wow,  i was under the impression the 3rd model was significantly larger than the 12th. You learn something new every day. Thanks!

What are the differences between the 12th and 3rd other than that .25"?

the 3rd mounts directly  to the 1/2x28 barrel threads - NOT to a muzzle brake.
